REVERSIBLE BROOM.

Application filed January This invention relates to a broom having a detachable reversible filler and the principal objects thereof are to provide an improvement in the reversible filler by which two advantages are secured. In the first place, short strands of broom corn can be used and in the second place. thethinner ends of these strands are at the end of the broom, where they are used, thus avoiding the presence of thick and unyielding ends.

The invention also involves an improved holder for the tillers which will not injure them and will secure them firmly and which can be located in two places at different distances from the handle to provide for holding within it a. set of bristles that is mate rially worn off at theend; also a surround ing holding means for the bristles and im-- proved means of securing the bristles together and holding them together.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings in which- Fig. 1 is a side view of a preferred embodiment of the invention;

Fig. 2 is an edge view showing the casing open; a

Fig. 3 1s a sectional view on the line 33 of Fig. 1;

Fig. 4 is a sectional view on the line 44 of Fig. 1 on enlarged scale;

Fig. 5 is a fragmentary side view somewhat enlarged and modified;

Fig. 6 is an edge view of two sets of short bristles which are to be connected as indicated in Fig. 7; and

Fig. 8 is a longitudinal sectional view of the same showing an improved fastening means for holding the bristles.

As stated, this invention relates to that type of broom in which the filler is removable from a holder and is also reversible end for end. In Fig. 6 I have shown two bunches of broom corn each much shorter than can i and is intended to penetrate all through them. It tends to remain sticky for a long 28, 1925. Serial No. 5,330.

time. Each bundle is then bound around with twine 11.

A series of bundles may be gathered together, asshown in the other figures, especially Fig. 4, and a cloth or tape is placed around the series or a simple metal band 9 as shown in Fig. 5 or in the preferred form, a double metal strip 12. This strip extends all the way around the series or bimdies to form a single broom head. Also. to prevent the bristles moving endwise, I place transverse pins, nails, or other fastening devices 13 across the several bundles and then through the whole set of bundles I place another pin or rod l-l transversely to them. These pins are all headed on one side and the points headed over on the other. They all extend twice through the metal strip 12. This metal strip provided with an into gral side flange 15 on one edge and on the other edge there is a longer flange 16 which. after application to the bristles, is bent over all around, as shown especially in Fig. 8, for the purpose of covering the nail heads and furnishing a strong and complete binder for the-whole set of bristles. This completes the formation of the removable and reversible brush head or filler. It ill be seen that it has two ends substantially alike so that when reversed there will be no difference in the character of the brush.

The metallic flange '16 is pierced with perforations 17, preferably four in number, on each side for receiving two series of wires 18 and 19. One set of wires 19 is pivotally attached and the other 18 rigidly. These wires are used for anchoring this binding strip and consequently the brush head to a casing 20. They are located bot-h on front and back of said casing and the casing is provided with perforations 21 for receiving both sets of wires-when the brush is used in the condition shown in Figs. 1 and 2. and with another set of perforations 22 farther back for receiving the same wires when the brush is worn at one end and has to be shoved baclrfarther in the casing 20.

The casing is provided with a hinged cover plate 23 and of course it is this cover that receives the perforations on one side.

The casing is formed of sheetmetal tapering 7 both ways to receive the brush head and allow the bristles to flare, as indicated. On the two edges near the open ends the metal casing'is bent out to form recesses 24 for receiving a pair of fastening devices 25, in

the form of wires having a straight back and two parallel legs. These can be turnd in notches 24. to the position shown in Fig". 1, for holding the cover in position or to a position. in which they project away from the cover so as not to engage it and allow it to be released, as shown in Fig. 2.

The casing 20 fastened Lll' around a wooden block 2? wl c across it within and which has a mi grooves 28 for receiving the iuturi of the casing on oppfiite sides and i it in position. It is also held in positio a pair of rivets F29 extendi' across it.

1 e cud 'cnds no block 27 is provided will grooves down its ends in which rest the ends 30 of a coil spring; 31 or a pair of them. These ends are bent in toward each other at the bottou'i of this block and, the spring a straight coil spring located in a concave depression in'the top of the block and QXLQlltllllQ' entirely across the top of it. I prefer to tin-m this s nnn from a single piece of wire. This wire is bent at the center to term a loop 32 which, of course, being forn'ied 0t two pieces of wire,

is twice as wide one way as the other. These two wires are twisted together at 33 r purpose to be described and then are senarated to form two springs 3i which it i referred to as a single spring: because they The end formed ot the parts and 33 is driven into a hole in the end of the wooden handle 34. On account of the tlat shape ot the loop 32, this will. not turn in the hai'idle after. it has been ins rted. A metal collar 35 is screwed on the twisted who being pen forated with a hole to receive it. {in account of this particular construction it cannot. work loose endwise. It is secured to the end of the wooden handle by a nail or the like and on account of that the terrulc cannot be turned. Therefore the handle cannot. work loose either by turning! or by longitudinal motion. This constitutes a very secure and firm way of holding it.

In operation, the handle being: connected with the head or casing 520 by the spring 3i. a yielding action is secured and this is pun ticula-rly valuable in case of the use of short bristles of less than the ordinary length because it gives the feel of the bristled broom and the effectiveness. The casing 20 constindapted to engage the outer sr tutes a holder for the bristles which, by means of the cover s3 and the devices 25, securely holds them in place and yet they are easily and readily detachable. The wires 18 and 19 hold the metallic binding strip 12 and therefore the brush head accurately in position and allow some flexibility between the casing and the center of the brush head. This is also detachable to receive the brush when the bristles are shortened by wear alter reversal. The use of the short bristles which are a waste product, is a great advantage for several reasons as has been stated. The brush head is nude in a very simple and convenient way and yet the parts are perinancntly connected by several securing devices that have been shown and described. It COIL 'stitutes a material improvement over the retherefore. i all the details oi construction herein shown and described but what I do claim is i. In a. hrooun the combination of a casing for holding); the broom head, said casing havinn converging sides and ends and havinga cover constituting one side hinged to the rest of the casino. and a pair ot wires pirotaily mounted in the opposite edges ot' the casing and each adapted to be t irned on itselt'as an axis and each having two parallel ends taco ot the cover and the op iosite surtace ot the casing
